CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority under 35 U.S.C. §119 to Korean Patent Application No. 10-2015-0022528, filed on Feb. 13, 2015, in the Korean Intellectual Property Office, the contents of which are incorporated by reference herein in their entirety.

TECHNICAL FIELD

The present invention relates to a liquid crystal display and a manufacturing method thereof.

DISCUSSION OF THE RELATED ART

A liquid crystal display, which is one of the most commonly used types of flat panel displays, includes two display units with electric field generating electrodes such as a pixel electrode and a common electrode. A liquid crystal layer may be interposed between the pixel electrode and the common electrode. The liquid crystal display generates an electric field in the liquid crystal layer by applying a voltage to the electric field generating electrodes. The electric field generated by the voltage applied to the electric field generating electrodes may change the direction of liquid crystal molecules of the liquid crystal layer. Thus, the liquid crystal display may control polarization of incident light and may display images.

Since the liquid crystal display is not a self-emission display device, a backlight for supplying light to the liquid crystal layer is utilized.

The liquid crystal display may be assembled by supporting a backlight assembly on a bottom chassis, mounting a liquid crystal panel on the backlight assembly, coupling the liquid crystal panel and the backlight assembly with each other using a top chassis, and attaching reinforced glass on an upper surface of the top chassis using an adhesive. In this case, the top chassis may have an upper surface covering an edge of the liquid crystal panel.

Recent demand for large liquid crystal displays having a small thickness has increased. A bezel area of the liquid crystal display may be defined by the bottom chassis and the top chassis and may be located at the edges of the liquid crystal panel. The bezel area of the liquid crystal display may be narrow (e.g., small). Alternatively, the bottom chassis and the top chassis may be omitted and the liquid crystal display may be configured to hide the bezel area from a user.

A portion of a substrate without a driving connection line of the two substrates facing each other may be partially removed at an edge portion with the driving connection line to expose the driving connection line. The driving connection line may be connected to an external driving circuit portion to transfer a driving signal to the liquid crystal panel. A height difference between the two substrates may be caused by the partial removal of one of the two substrates (e.g., to expose the driving connection line). The height difference between the two substrates may be compensated by a chassis.

SUMMARY

Exemplary embodiments of the present invention have been made in an effort to provide a liquid crystal display and a manufacturing method thereof that prevent a bezel portion from being viewed by a user at four edges of a liquid crystal panel by omitting a chassis part even at the portion corresponding to the edge with the driving connection line connecting an external driving circuit portion and a liquid crystal panel.

DETAILED DESCRIPTION OF THE EMBODIMENTS

The present invention will be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the present invention are shown. As those skilled in the art may realize, the described embodiments may be modified in various different ways without departing from the spirit and scope of the present invention.

It will be understood that when an element such as a layer, film, region, or substrate is referred to as being “on” another element or “adjacent” to another element, it may be directly on or adjacent to the other element or intervening elements may also be present. A liquid crystal display, according to an exemplary embodiment of the present invention, may be described with reference to FIGS. 1 to 4. FIG. 1 is a layout view of a liquid crystal display according to an exemplary embodiment of the present invention. FIG. 2 is a cross-sectional view of the liquid crystal display of FIG. 1 taken along line II-II′, according to an exemplary embodiment of the present invention. FIG. 3 is a cross-sectional view of the liquid crystal display of FIG. 1 taken along line III-III′, according to an exemplary embodiment of the present invention. FIG. 4 is a cross-sectional view of the liquid crystal display of FIG. 1 taken along line IV-IV′, according to an exemplary embodiment of the present invention.

Referring to FIGS. 1 to 4, a liquid crystal display 10, according to an exemplary embodiment of the present invention, may include a first display panel 100 and a second display panel 200 facing each other and coupled to each other. The liquid crystal display 10 may include a first polarizer 11 disposed on the first display panel 100, a second polarizer 21 disposed on the second display panel 200, and a reinforcing part 50 disposed on a surface of a portion of the first display panel 100 which does not overlap with the second display panel 200. The liquid crystal display 10 may include a liquid crystal panel 20, the liquid crystal panel 20 including the reinforcing part 50, a film layer 60 disposed on the surface of the second polarizer 21, the first and second display panels 100 and 200, the first polarizer 11, and the second polarizer 21. A backlight unit 300 may be disposed on a surface of the liquid crystal panel 20.

The backlight unit 300 may include a backlight assembly 31 and a mold frame 32 fixing the backlight assembly 31.

The liquid crystal panel 20 and the backlight unit 300 may be coupled (e.g., attached) with each other by an adhesive part 40.

Referring to FIG. 1, the liquid crystal panel 20 may include a first display panel 100 and a second display panel 200 facing each other and coupled with each other. The liquid crystal panel 20 may include a display area DA in which a plurality of pixels may be formed to display an image.

Referring to FIGS. 2 and 3, in an exemplary embodiment, the second polarizer 21 may extend up to both edge ends of the liquid crystal panel 20 in an X direction, and may not extend to both edges of the liquid crystal panel 20 in a Y direction. For example, the second polarizer 21 may extend on a portion of the liquid crystal panel 20 which overlaps with the mold frame 32 of the backlight unit 300 and the adhesive part 40.

The first polarizer 11, which may be disposed on the first display panel 100 adjacent to the backlight unit 300 of the first and second display panels 100 and 200 of the liquid crystal panel 20, might not be formed on a region where the adhesive part 40 is disposed. The second polarizer 21, which is disposed on the second display panel 200, may extend up to a region overlapping with the adhesive part 40, and may not overlap with the driver connecting line CL.

In an exemplary embodiment, the second display panel 200 does not overlap with an edge of the first display panel 100 where the driver connecting line CL is formed. For example, a width of the second display panel 200 along the Y direction may be smaller than a width of the first display panel 100 along the Y direction. The second display panel 200 may not overlap with a vicinity of the edge of the first display panel 100 where the driver connecting line CL is formed. Accordingly, an edge portion of the first display panel 100 may be exposed, and at least a part of the driver connecting line CL of the first display panel 100 is may be exposed on the exposed edge portion of the first display panel 100.

The second polarizer 21 may be disposed on the second display panel 200 and may overlap with the second display panel 200. The second polarizer 21 may not overlap with an edge portion of the first display panel 100 where the driver connecting line CL is disposed.

The reinforcing part 50 may be disposed on an edge portion of the first display panel 100 where the driver connecting line CL is disposed.

The reinforcing part 50 may compensate for a difference in height between a portion of the first display panel 100 where the driver connecting line CL is disposed and other components of the liquid crystal display 10 such as the second display panel 200, the second polarizer 21, or the film layer 60. For example, a step formed where the first display panel 100 does not overlap with the second display panel 200 may be compensated (e.g., filled) by the reinforcing part 50. Accordingly, a height of a surface (e.g., top surface) of the second polarizer 21, disposed on a surface of the second display panel 200, and a height of a surface (e.g., top surface) of the reinforcing part 50 may be substantially equal to each other.

According to an exemplary embodiment of the present invention, a thickness of the reinforcing part 50 may be about 0.5 mm to about 0.7 mm.

The film layer 60 may be disposed on the surfaces of the reinforcing part 50 and the second polarizer 21, and may cover substantially the entire surface of the liquid crystal display 10. For example, the film layer 60 may cover both the reinforcing part 50 and the second polarizer 21 to prevent a step between the reinforcing part 50 and the second polarizer 21 from being viewed by the user.

The film layer 60 may be a protective film. The thickness of the film layer 60 may be increased to prevent the step between the reinforcing part 50 and the second polarizer 21 from being viewed by the user. However, to produce a thin liquid crystal display, the thickness of the film layer 60 may be about 180 μm to about 250 μm.

In a liquid crystal display, according to an exemplary embodiment of the present invention, a chassis may not be disposed between the liquid crystal panel 20 and the backlight unit 300 which contact each other.

In a liquid crystal display, according to an exemplary embodiment of the present invention, after the backlight assembly 31 is fixed by the mold frame 32, the backlight assembly 31 is adhered to the liquid crystal panel 20 using the adhesive part 40. Thus, the liquid crystal panel 20 and the backlight unit 300 may be attached (e.g., adhered) to each other at four edges of the liquid crystal display 20 without using a top chassis. Thus, a thickness and a weight of the liquid crystal display may be reduced and a width of the bezel portion may be reduced.

In a liquid crystal display, according to an exemplary embodiment of the present invention, after the second polarizer 21 is formed on the surface of the second display panel 200, the reinforcing part 50 is formed between a portion of the first display panel 100 which does not overlap with the second display panel 200 to compensate for the elevation difference between the top surface of the first display panel 100 and the top surface of the second polarizer 21.

FIG. 12 is a cross-sectional view taken along line IV-IV′ in a liquid crystal display according to a comparative example of the present invention.

Referring to FIG. 12, the liquid crystal display according to the comparative example may include a reinforcing part 50 disposed on a portion of the first display panel 100 which does not overlap with the second display panel 200. A second polarizer 21 may be disposed on the second display panel 200 and the reinforcing part 50. As a result, in the liquid crystal display according to the comparative example, the reinforcing part 50 is formed at the portion of the first display panel 100 which does not overlap with the second display panel 200, and then the second polarizer 21 may be formed on the second display panel 200 and the reinforcing part 50.

In this case, since the second polarizer 21 is formed after the process of forming the reinforcing part 50, stains may be generated on a surface of the second display panel 200 when the process of forming the reinforcing part 50 is performed. Accordingly, in a liquid crystal display according to the comparative example, before forming the second polarizer 21 on the reinforcing part 50 and the second display panel 200, a process of cleaning the surfaces of the reinforcing part 50 and the second display panel 200 is required.

However, as illustrated in FIG. 4, in a liquid crystal display according to an exemplary embodiment of the present invention, since the second polarizer 21 is formed to overlap with only the surface of the second display panel 200, the reinforcing part 50 may be formed after forming the second polarizer 21. Accordingly, in a liquid crystal display according to an exemplary embodiment of the present invention, a process of cleaning the surfaces of the reinforcing part 50 and the second display panel 200 before forming the second polarizer 21 may be omitted. Accordingly, a manufacturing process of a liquid crystal display 10 may be simplified and manufacturing costs of the liquid crystal display 10 may be reduced. A structure of the reinforcing part 50 of the liquid crystal display 10, according to an exemplary embodiment of the present invention, will be described in detail with reference to FIG. 5. FIG. 5 is a cross-sectional view of a reinforcing part, according to an exemplary embodiment of the present invention.

Referring to FIG. 5, a reinforcing part 50 of the liquid crystal display 10, according to an exemplary embodiment of the present invention, may include a first layer 51 a, a second layer 51 b, and an adhesive layer 52 for coupling the first layer 51 a and the second layer 51 b.

The first layer 51 a and the second layer 51 b may include synthetic resins such as polyethylene (PET).

At least one of the first layer 51 a and the second layer 51 b may include an elastic body (e.g., an elastic material). The elastic body of the first layer 51 a or the second layer 51 b may be included in at least a portion of a layer of the reinforcing part 50 (e.g., a portion of the first layer 51 a or the second layer 51 b). As a result of the elasticity of the reinforcing part 50, if a small height difference between a top surface of the reinforcing part 50 and a top surface of the second polarizer 21 exists, a surface (e.g., a top or a bottom surface) of the film layer 60 may be prevented from being lifted when the film layer 60 may be disposed on the top surface of the reinforcing part 50 and the top surface of the second polarizer 21. The reinforcing part 50 of the liquid crystal display 10, according to an exemplary embodiment of the present invention illustrated with reference to FIG. 5, may have a triple-layer structure including the first layer 51 a, the second layer 51 b, and the adhesive layer 52 for coupling the first layer 51 a and the second layer 51 b. However, a reinforcing part 50 of a liquid crystal display 10, according to an exemplary embodiment of the present invention, may have a single-layer structure, a double-layer structure, a quadruple-layer structure, or a structure including more than four layers.

A manufacturing method of a liquid crystal display, according to an exemplary embodiment of the present invention, will be described with reference to FIGS. 6 to 11 and FIGS. 1 to 4. FIGS. 6 and 9 are cross-sectional views of the liquid crystal display 10 illustrated in FIG. 1, taken along line illustrating a manufacturing method of a liquid crystal display according to an exemplary embodiment of the present invention. FIGS. 7 and 10 are cross-sectional views of the liquid crystal display 10 illustrated in FIG. 1, taken along line illustrating a manufacturing method of a liquid crystal display according to an exemplary embodiment of the present invention. FIGS. 8 and 11 are cross-sectional views of the liquid crystal display illustrated in FIG. 1, taken along line IV-IV′, illustrating a manufacturing method of a liquid crystal display according to an exemplary embodiment of the present invention.

As illustrated in FIGS. 6 to 8, the first display panel 100 including the driver connecting line CL and the second display panel 200 are formed, the first display panel 100 and the second display panel 200 face each other and are coupled to each other, and a liquid crystal layer is injected between the first display panel 100 and the second display panel 200. The first polarizer 11 is then attached to the first display panel 100, and the second polarizer 21 is attached to the second display panel 200. In a manufacturing method of the liquid crystal display, according to an exemplary embodiment of the present invention, the first polarizer 11 is attached after the first display panel 100 and the second display panel 200 are coupled to each other. However, exemplary embodiments of the present invention are not limited thereto.

For example, in a manufacturing method of a liquid crystal display according to an exemplary embodiment of the present invention, the first display panel 100 including the driver connecting line CL is formed, the first polarizer 11 is attached to the first display panel 100, the second polarizer 21 is attached to the second display panel 200, and then the first display panel 100 and the second display panel 200 may be coupled to each other. Various manufacturing sequences may be used to dispose the first polarizer 11 on the first display panel 100, to dispose the second polarizer 21 on the second display panel 200, and to couple the first display panel 100 with the second display panel 200. The first display panel 100 and the second display panel 200 may face each other. An external driving circuit part DP may be connected to the driver connecting line CL of the first display panel 100. The reinforcing part 50 may be disposed on the driver connecting line CL exposed (e.g., disposed) at one edge portion of the first display panel 100. In a manufacturing method of a liquid crystal display according to an exemplary embodiment, the reinforcing part 50 may be disposed on the driver connecting line CL after the driver connecting line CL and the driving circuit part DP are connected to each other. However, exemplary embodiments of the present invention are not limited thereto.

For example, in a manufacturing method of a liquid crystal display according to an exemplary embodiment of the present invention, after the reinforcing part 50 is formed on the driver connecting line CL exposed outside at one edge of the first display panel 100, the external driving circuit part DP may be connected with the driver connecting line CL.

As illustrated in FIGS. 9 to 11, the backlight unit 300 and the first display panel 100 may be attached to each other using the adhesive part 40. In a manufacturing method of a liquid crystal display according to an exemplary embodiment of the present invention, the reinforcing part 50 may be disposed on the first display panel 100 before the backlight unit 300 and the first display panel 100 are attached to each other using the adhesive part 40. However, exemplary embodiments of the present invention are not limited thereto.

For example, in the manufacturing method of a liquid crystal display according to an exemplary embodiment of the present invention, the reinforcing part 50 may be formed after the backlight unit 300 and the first display panel 100 are attached to each other using the adhesive part 40.

In a manufacturing method of the liquid crystal display according to an exemplary embodiment of the present invention, the process of forming the second polarizer 21 to overlap with only a surface of the second display panel 200 is performed. As a result, after the process of forming the second polarizer 21, the process of forming the reinforcing part may be performed. Accordingly, in a manufacturing method of a liquid crystal display according to an exemplary embodiment of the present invention, the process of cleaning the surfaces of the reinforcing part 50 and the second display panel 200 may be omitted before the process of forming the second polarizer 21. Accordingly, a manufacturing process of the liquid crystal display 10 may be simplified, and the manufacturing cost of the liquid crystal display 10 may be reduced.

As illustrated in FIGS. 1 to 4, the film layer 60 may be disposed on the second polarizer 21 and the reinforcing part 50. As a result, the film layer 60 may be disposed on the entire surface of the liquid crystal display 10.

In a manufacturing method of a liquid crystal display according to an exemplary embodiment of the present invention, the second polarizer 21 is formed on the second display panel 200, the reinforcing part 50 is formed at a position overlapping with the driver connecting line CL formed on the first display panel 100, and then the film layer 60 may be formed on the entire surface of the liquid crystal display 10 by attaching the film layer 60 to the second polarizer 21 and the reinforcing part 50. Therefore, the bezel portion of the liquid crystal display 10, at four edges of the liquid crystal display 10, may be substantially hidden from a user of the liquid crystal display 10.

While the present invention has been described with reference to exemplary embodiments thereof, it is to be understood that the present invention is not limited to the disclosed exemplary embodiments.
